What do clay masks actually do?

As reported by Dermstore, Peter Konish, Director of Product Development at Johnson & Johnson explained that, "Clays help to detoxify the skin and draw out impurities and oils from the surface of the skin."

He added, "This is especially helpful to those people with acne or oily-prone skin."

While clay masks can help to detoxify the skin, the product also has hydrating and oil absorption benefits. As Konish put it, "It helps draw out the impurities as well as absorb excess oils that are on the surface of the skin. Additionally, it helps reduce excess shine."

How do clay masks work?

According to Alitura Naturals, clay masks work by soaking up anything and everything that may be clogging up your skin.

The website explains, "After application of a clay mask, you will feel your face tighten as the clay dries. As the clay dries it "soaks" up the skins natural oils and anything clogging the pores and draws it to the surface."

So, what should you be on be look out for?

Skincare.com consultant Dr. Dhaval Bhanusali explained, that when choosing a clay mask, it's good to look for one specific ingredient, "Kaolin is an important ingredient to be on the lookout for." Also know as white clay, Kaolin is quite mild, and can help to draw out oils without being harsh on the skin.

Dr. Neal Schultz, NYC dermatologist, echoed these sentiments in talking to Bustle, "In terms of important ingredients, look for kaolin and/or bentonite as superior ingredients for these types of masks."

Dr. Lortscher, CEO and Founder of Curology added, "Bentonite and kaolin clay also draw out water and oil from your skin, which may temporarily make pores appear smaller."

How do you maximise its impact?

Finally, Konish explains that a clay mask will have maximum impact when it's followed by your regular skincare routine, so don't forget to cleanse and moisturise after removing the clay.
